檢測某個php進程運行狀態shell

檢測某個php進程shell腳本

一.主要shell代碼

#!/bin/bash
executePath=$(readlink -f $(dirname $0))
executeLog=`readlink -f  $executePath/check.log`
envPath=`readlink -f  $executePath/../../env.sh`
source $envPath
set -a; source /etc/environment; set +a;
scriptIndex=`readlink -f  $executePath/../console/index.php`
proccessName=common/test/index
proccessNum=`ps aux|grep -v grep|grep $proccessName|wc -l`
needNum=1
if [ $1 ]
then
    proccessName=$1
fi
if [ $2 ]
then
    needNum=$2
fi
function setProccessNum
{
    proccessNum=`ps aux|grep -v grep|grep $proccessName|wc -l`
}

function stop_pro()
{
    pids=$(ps aux|grep -v grep|grep common/test/index|awk '{ print $2 }')
    for pid in $pids
    do
        setProccessNum
        if [ $proccessNum -eq $needNum ]
        then
            break
        fi
        kill -9 $pid
    done
}

function start_pro()
{
    setProccessNum
    while (( $proccessNum < $needNum ))
    do
        /usr/local/php/bin/php $scriptIndex $proccessName   &
        setProccessNum
    done
}

if [ $proccessNum -lt $needNum ]
then
    echo  "實際進程數爲:"$proccessNum"需要進程數爲:"$needNum"增加進程數..."
    start_pro
elif [ $proccessNum -gt $needNum ]
then
    echo "實際進程數爲:"$proccessNum"需要進程數爲:"$needNum"減少進程數..."
    stop_pro
    sleep 1
    start_pro
fi

二.使用說明

1. 將代碼寫入文件,路徑與項目需要自行調整
2. 加入定時linux任務檢測
